Identification of Graphite Mechanical Behavior and Dislocations by Micro-Raman MicroscopyIn this study, micro-Raman microscopy was used to examine graphite mechanical behavior through the evolution of dislocation defect density and the resultant deformation (strain) in graphite components. The increasing strength of the Raman optical phonon modes linked with a generous number of dislocations indicates the potential capability of Raman spectroscopy to help develop a mechanistic understanding of the complex mechanical behavior of graphite for use in many industries and applications.

Deep Learning Advances Gas Quantification Analysis in Near-Infrared Dual-Comb SpectroscopyResearchers from Tsinghua University and Beihang University in Beijing have developed a deep-learning-based data processing framework that significantly improves the accuracy of dual-comb absorption spectroscopy (DCAS) in gas quantification analysis. By using a U-net model for etalon removal and a modified U-net combined with traditional methods for baseline extraction, their framework achieves high-fidelity absorbance spectra, even in challenging conditions with complex baselines and etalon effects.
